The NBN won't carry long-haul, except I suppose for its own corporate 
network traffic, which it would buy from a fibre owner.

Intercity fibre is outside the NBN's brief, with an exception I'll get 
to in a second.

Take Sydney-Melbourne: there are at least four carriers operating their 
own fibre on that route - Telstra, Optus, AAPT and Nextgen - and where 
routes are contested and have heavy traffic, prices aren't a problem. So 
it would be completely superfluous to have an NBN-operated fibre on 
those routes.

Also remember that NBN Co is a wholesale-only operator: it will not 
offer inter-city WAN services, because that's a retailer's job.

The long-haul exception is where Telstra is the only operator of a 
long-haul fibre. The NBN operator is allowed to build its own fibre in 
that case.
